Use tooltips instead of labels for VoxelGI and GPUParticlesCollisionSDF

This fixes the issue with labels being cut off (or becoming too long
when not clipped).

This also adds a mention of the individual cell size,
which is useful information to have when trying to avoid light leaking
or particle collision tunneling.
